Loads and restraints are necessary to define the service environment of the model. The results of analysis directly depend on the specified loads and restraints. Loads and restraints are applied to geometric entities as features that are fully associative to geometry and automatically adjust to geometric changes.
For example, if you apply a pressure P to a face of area A1, the equivalent force applied to the face is PA1. If you modify the geometry such that the area of the face changes to A2, then the equivalent force automatically changes to PA2. Remeshing the model is required after any change in geometry to update loads and restraints.
When you create a study, the program creates a Load/Restraint folder in the COSMOS AnalysisManager tree. The software adds an item in the Load/Restraint folder for each load or restraint you define on one or more entities.
The types of loads and restraints available depend on the type of the study. A load or restraint is applied by the corresponding PropertyManager accessible by right-clicking the Load/Restraint folder of a study in the COSMOS AnalysisManager tree, or by clicking COSMOSWorks, Loads/Restraint. Other types of structural loads are available via special functions like importing loads from COSMOSFloWorks or COSMOSMotion.
To help you define studies faster, you can
drag and drop Load/Restraint folders and items from one study to another
compatible study in the COSMOS AnalysisManager tree. You can also copy
studies and other folders and items.
